How to do these?
18.Energy is an extensive quantity and depends on the amount of substance. In this case you are using 1/5 the amount of ammonium nitrate, so 1/5 the amount of energy is absorbed.
As q= mcΔT and the mass and c are constant then q is proportional to ΔT
19. Combustions are useful in determining energy change, and the formation of water is also the combustion of hydrogen.
